A Latin American Economist, Professor Di Tella has taught at Harvard Business School since July 1997. His work has focused on the political economy, with a focus on institutional development. One strand of work studies measures of happiness and how they may inform government policies on issues that range from the incidence of inequality to the inflation-unemployment tradeoff as well as the role of beliefs in economic organization, including reversals of pro-market reform and, more generally, why doesn't capitalism flow to poor countries.
